National Briefing | South: Puerto Rico: U.S. Seizes Polar Bears

Federal authorities seized six polar bears from a Mexican circus touring in Puerto Rico, saying the circus had violated the Marine Mammal Act by keeping the animals caged in the Caribbean heat. Federal marshals were guarding the bears in Yabucoa, a southern Puerto Rican city, until they could be transferred at the end of the week to the Detroit Zoo, the Department of Justice said. The circus, Suarez Brothers of Guadalajara, which was touring elsewhere in the Caribbean, was not available for comment.
